Youth consuming inadequate amounts of calcium are at risk of developing osteoporosis later in life. To better assess dietary calcium intakes and the efficacy of dietary intervention strategies to improve bone health among youth, it is important to develop calcium intake assessment tools that are reliable, accurate, and interactively engaging for a new generation of youth who have a higher computer literacy and are more technologically knowledgeable than preceding generations. The goal of this dissertation was to develop and evaluate an electronic food frequency questionnaire ( eFFQ) that measures calcium intake among 11-to 18-year-old Asian, Hispanic, and White youth. Enhancing this tool was the inclusion of 100 original digital color food photographs portraying the foods listed in the eFFQ. A formal evaluation study, as well as formative and summative evaluations of food photos and the eFFQ, was accomplished.
